At long last, the entire 158 card visual spoiler for Dark Ascension was released today and that means over the next week or two I'll be writing up First Impressions & Deck Ideas for the remaining 79 cards of the set. Let's get started:
This might take me a while for me to wrap my head around. I'm not sure what Archangel's Light is better than on a whole because it's definitely not better than existing cards out there in parts.
If you wanted a card that shuffles your graveyard into your library which also gives you life, Elixir of Immortality is a much better choice as its converted mana cost is affordable for any deck. Even still, it's important to note that Elixir of Immortality also shuffles itself back into your library while Archangel's Light does not. If you wanted a card that gave you life based on the number of cards in your graveyard, Ancestral Tribute does the same and it does it twice. Because of this, if you would want to squeeze Archangel's Light into a deck, that deck would have to be very specific.
In the end, I think this is a very poor card when judged against the Legacy card pool. Because it's not a repeatable effect and because it costs so much to cast, what deck would you actually use this in? From a design point of view, I think they could have shaved a few colorless mana off the top. 8cc is too much for its effect.
Off the top of my head, I can't think of anything except to maybe find a way to combo this with Chalice of Life. If Gnaw to the Bone can already consistently net a player 30+ life after a lot of self-mil, Archangel's Light could do the same, much quicker.
--Of course it doesn't have flashback and is actually much worse for a self-mill deck that wants to gain life.
But maybe the deck wouldn't have to adapt a self-mill strategy at all? Maybe you could just throw a couple Archangel's Lights and Chalices of Life into a white deck and that would be enough to break the 30+ life threshold?
Not sure. This needs further testing. But as of right now, I stand by original assessment and say this is a very bad card.
